Since everyone here seems to love cursed technology, I made a chart rating various interfaces by their perceived cursedness.

Some like 10G BASE-T have a reason for being cursed, whereas others like USB PD not so much.

Any additions?

An X/Y chart with the X axis labeled 'fast [bit/s]' and the Y axis labeled 'cursed'. On the X, axis there are log-spaced ticks from 100k to 10G.

The chart area is filled with various interface names, listed in order of ascending cursedness:

100k Range:
UART, TI Calculator link cable, USB PD

1M/10M Range:
SPI, CAN, USB, FS

100M/1G Range:
USB 3.0, 100Base-T, D-PHY, 1000BASE-T, USB HS, HEC, MHL

10G Range:
PCIe, USB4 v2, 10G BASE-T

@karotte irda. It's UART but optically cursed.
TOSLINK? Barely cursed at all, unless you try and make it cross the Atlantic.

@karotte might make sense to add SATA, Isa and pci (no e)

How do you determine the cursedness? Is it how hard the interface is to implement, or how the world will perceive you trying to bit-bang it, or some particular quirks that stand out but are needed for backwards compatibility or other reasons?

Remember back when there was no Chrome, Internet Explorer was the enemy and Firefox the hot new thing?

Believe it or not, this video got the second place in the 2006 Firefox ad contest: blog.mozilla.org/press/2006/04

@karotte I really like this. where did you get the video from? (firefoxflicks.com seems to be dysfunctional :()

@karotte nop, i don't remember it. Firefox was old when chrome was first released.
Before Chrome it was IE (supported by all sites, but shitty browser used by most people), Firefox and Opera fighting to be best alternative browser, and Safari for Jobs fanclub

@karotte kexec -- when panicking your kernel trumps waiting for a minute.

[evil] witch lexi :red_pentacle:

@karotte@chaos.social this'll be interesting. especially since init often checks it's own PID. what exactly happens?

It's project time again!!!

For a future project, I need to conveniently probe an SFP transceiver while it's operating. Not having found an SFP extender that suited my needs, I made my own based on an HDMI cable.

The SFP end on the top goes into a 3D-printed shell.

The receptacle board fans out all low-speed signals to headers for convenient probing and interception. It can be cut at the white line to get access to the bottom side of the SFP.

1GE link works, 10GE is to be tested.

Two green PCBs on a grey metal surface, connected by a mini HDMI to HDMI cable

The top one is roughly the size of an SFP transceiver, has an edge connector on the right edge, a mini HDMI receptacle on the left edge and is labeled "SFP extender".

The bottom one is is 50×80mm and is populated with an HDMI receptacle labeled "NOT HDMI", a set of pin headers and an SFP receptacle without the cage.
